The White Sox rookie count on the 25-man roster now stands at 10, including eight pitchers. The latest to join the team is right-hander Deunte Heath, who arrived Wednesday to replace veteran Jesse Crain.
Crain went on the 15-day disabled list retroactive to June 24 with a right posterior shoulder strain.
Heath, 26, is 4-2 with a 1.70 ERA over 42 1/3 innings with one save and 46 strikeouts in 22 games. Three of his games were starts, including the last two outings in which he threw four innings. That would make him a candidate to start Sunday's game, the Sox' last before the All-Star break.
Heath will wear uniform No. 60. He has no major-league experience.
Crain is 2-1 with a 2.38 ERA. He was on the disabled list from April 27-May 14 with a strained right oblique.
